Files are displayed empty after restart of the container #114

Closed artem-german closed 1 year ago

artem-german commented 1 year ago

Hi there,

thanks a lot for this great project, first of all!

We noticed the following problem: after starting the Docker and working there, everything goes well. Then, when we need to stop and start it again for whatever reason, when we try to open any file already in the working directory, it's shown in the browser as an empty file. However, when looking into the filesystem, the contents are still present.

This also still is the case after starting a fresh docker with the same data. Adding all the files and directories using the upload in Jupyter is not a feasible solution.

Used version is: v1.5_cuda-11.6_ubuntu-20.04_python-only

Also: --collaborative is active

Any idea how to fix this?

All the best,

Artem.

Found a solution, which wasn't a problem with the container at all, but with the reverse proxy. Apparently websocket support is needed to display the files. See the following link for information (with nginx), which helped me solve the problem:

Closing issue. :)
